LAMP-BURNER.

Specification of Letters Patent.

` Patented May 28, 1907.

Application led January 7,1907. Serial No. 351,122.

To a/Z/ whom t 711/007./ concern:

Be it known that I, ALEXANDER H. HAND- LAN, Jr., a citizen of the UnitedStates of America, residing in the city of St. Louis and State ofMissouri, have invented certain new and useful Improvements inLamp-Burners, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing, formingpart of this specification.

My invention relates to a lamp burner for use in burning petroleum orother hydrocarbon oils and it has for its object to provide a greaterilluminating power in a burner of this character by the use of twin wicktubes and av twin guard applied to the upper ends of said twin wicktubes and serving to prevent a strong upward draft at the point wherecombustion takes place, thereby providing for the flames emitted fromthe burner spreading toward and merging into each other instead of beingcarried upwardly by an'ascending air current caused by the heat of theflames.

Figure I is a view partly in side elevation and artly in verticalsection of my burner. Fig. I is a top or plan view of the burner.

1 designates the lower part of the base of the burner which is providedwith a screw threaded neck 2 having lower plate 1c and that is adaptedto be seated in a lamp font. The lower art 1 is also formed with anannular upper iange 1d. 1e is the upper part of the base having an upperplate 1 f and an annular lower fiange 1g underlapping the upper flange1d ofthe lower part 1.

3 are the twin wick tubes that are mounted in the plates 1C and 1f ofthe base parallel with each other.

4 designates a'downwardly tapering shell that isl detachably connectedto part 1c of the base and which has an inwardly extending base fiange 5that is provided with radial notches 6. The flange 5 is adapted to restupon a ledge 1a of the upper part 1e of the base and to engage beneathradial protuberances 1b that are struck outwardly therefrom above saidledge. The notches inthe shell flange receive these protuberances whenthe shell is to be connected to the base and when the'shell is rotatedon the base the flange becomes securely confined beneath saidprotuberances. The up er portion of the shell 4 is made of skeleton fbrmand has applied to it a perforated sheet 7 preferably of wire cloththrough which air is permitted to enter to the interior of the shell.The shell proper is surmounted by a conical ring S having a dependingrim 8b fitting around the vertical rim 5? of the shell, and a verticalcollar 8C which enters the lamp chimney.

9 designates an upwardly and outwardly flaring twin guard that is fixedto the twin wick tubes '3 near their upper ends and which comprises apair of segmental collars merged into and united to each other betweenYthe twin wick tubes, thereby rendering them of twin form and havingdepending tubes. Each of the segmental collars of said guard is attachedto its respective wick tube at a point considerably below the upper endof the wick tube, thereby providing a segmental channel surrounding eachwickntube and having communication with the segmental channel around theother wick tube. In the web which unites the two collars of the twinguard is an orifice 10.

During the use of my burner, the twin guard 9 acts to eifectuallyprevent air from passing upwardly adjacent to either of the wick tubesin the burner and therefore the iiames burning from the wicks in thesetubes when the illuminant is ignited are permitted to spread, due to theabsence of a direct draft of air thereagainst. The segmental collars ofthe twin guard being united by a web located beneath the upper end ofthe twin guard, connects these segmental collars in a manner to preventthe air from rising between the wick tubes and as a consequence theiiames burning from the two wicks merge into each other with the resultof affording a greatly increased .degree of illumination over what wouldbe possible in the use of the burner if the twin guard were absenttherefrom. The orifice 10 in the web of the twin guard is produced so asto provide an outlet for oil that may be drawn upwardly through the wicktubes by capillary attraction and unconsumed. By providing this orificeoil that fiows downwardly on the wick tubes is caught by the twin guardand is constantly drained from said twin guard instead of being allowedto accumulate therein.

11 designates chimney holding elongated spring fingers that are securedto the lower end of the. shell 4 and which extend vertically throughsaid shell and through radial slots 8 in the conical ring 8. Byextending these elongated spring fingers from the lower end of theburner shell through the radial slots in said conical ring, I providefor a more direct bearing of the elongated spring IOO iingers against achimney used upon the burner, due to the greater length of the elongatedspring fingers thus permitting the consequent longer leverage actionpresentin them.

I claim:

l. In a lamp burner, a base, a pair of Wick tubes supported by saidbase, and a guard attached to said tubes near their upper ends andcomprising a pair of segmental collar portions; said collar portionsbeing united by a horizontal Web located beneath the upper end of theguard, substantially as set forth.

2. In a lamp burner, a base, a pair of Wick tubes supported by saidbase, and a guard attached to said tubes near their upper ends andcomprising a pair of segmental collar portions; said collar portionsbeing united by a web containing an ori'licc, substantially as setforth.

3. A lamp burner comprising a base provided with lower and upper plates7twin Wick tubes secured in the plates, a twin guard consisting of mergedsegmental collars having depending tubes and lnoviding segmentalchannels and a connecting web having an oriiice.
